The CHIPS_PRT_FILE flow uses the Chips.prt file from an ALLEGRO-HDL symbol. The PIN_NUM, PIN_NAME are found included in this file and PartBuilder knows how to read and extract that information. The PIN_TYPE can also be encoded in the File. This is used by chip Vendors who create their packages using the Allegro Tool Flows.

Another use of the CHIPS_PRT_FILE flow is to re-partition symbols for a part using the pin information that already exists.
